TIE-GAININ'G MACHINE.
Specification of Letters Patent.
Patented June 1, 1915.
Application filed April 1,1913. Serial No. 758,172.
To all whom it may concern Be it known that we, Gnonon C. PURDY and DANIEL V17.v EDWARDS, citizens of the United States, residingat Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Tie-Gaining Machines, of which the following is a specification.
This invention relates to wood gaining machines, and more particularly to those adapted to gain railroad-ties.
An object of theinvention is to provide a machine which will gain all ties uniformly regardless of the varying irregularities thereof, that is, one in which the gaining cutters will gain the tie throughout the length of said cutters so that the gained portions shall be of a uniform predetermined depth. This object is accomplished by providing novel equalizing supports adapted to carry the tie while it is being gained.
A further object is to provide means for indicating the positions of said equalizing supports relative to the gaining tools, and also actuating means for positioning the supports in View of such indication, to gain at a predetermined uniform depth.
A further object is to construct improved devices adapted to cooperate in the gaining of the tie to secure a center of operation at each gained portion, such devices comprising tie carrying means and cushioned means for holding the tie in an operative position.
A further object is to construct a tie gaining machine in which the cooperating means acting upon one end of a tie, are adapted to be carried upon an adjustable carriage which may be moved over the bed of the machine transversely to the feed of the tie through the machine.
In the accompanying drawings, Figure 1 is a plan view of our improved gainingmachine. Fig. 2 is a side elevation of the machine looking at the feed entrance of the machine, the tie feed conveyors and equalizing control levers being omitted. Fig. 3 is an end elevation of the machine illustrating the control end. Fig. 1 is a vertical section on the line M of Fig. 1. Fig. 5 is a section on the line 5-5 of Fig. 1, the adjustable carriage having been moved toward the fixed carriage, and illustrating the positions, of the equalizing supports in relation to an irregular tie. Fig. 6 is a fragmentary side elevation of the adjustable carriage as shown at Fig. 2. Fig. 7 is a diagrammatic view illustrating the control of the equalizing support as shown in Fig. 6. Fig. 8 is an end elevation of the drive means only, at the drive end of the machine. Fig. 9 is a vertical section on the line 99 of Fig. 2, through the adjustable carriage. Fig. 10 is a section on the line 1010 of Fig. 2, of the air cushioned holding shoe, showing it in a lowered inoperative position.
The rectangular base 11 of the'machine has formed longitudially thereof, two parallel tracks 12 upon which are mounted two carriage or supporting frames 13 and 1 1, the frame 14 being fixedly secured thereto. The movable frame or carriage 13 is guided in position by the gib-plates 12 and is fed along the base by operating the hand-wheel 15, which is journaled in the supportingbracket 16 bolted to the base and carries a spur-pinion 17 driving with the spur-gear 18 j ournaled in bracket 16, said spur-gear 18 being keyed to the screw-shaft 19 that drives in engagement with the screw-bracket 20 bolted to carriage 13.
The two frames 13 and 14 and the several devices carried thereby are of a like construction, except for certain drive means having connection with frame 14:, so therefore we will describe the construction of but one frame broadly speaking, and the reference numerals as applied thereto will refer. to the like parts on both frames.
The frames 13 and 14 are each formed with a cutter casing 21 and laterally extending j o-urnal supports 22, frame 13 having an extending journal support 23 and frame 141 having a ournal support 21. Suitable means may be employed to operate the gaining cutters and tie conveyors, having here shown a main drive-shaft 25 journaled in supports 23 and 26, which drives a cormter-shaft 27 through means of the loose and driving pulley belt connections 28, said counter-shaft 27 driving a stud-shaft 29 by spur-pinion and gear 30, and the stud-shaft 29 driving the conveyor-shaft 31 journaled in supports 20, 22 and 24, through means of spur-pinion and gear 32. Journal bearings 33 carried by the frames are formed with supports 34 adjustable with the frames and carry a conveyor-shaft 35. Following more particularly the adjustable carriage 13, sprocket-wheels 36 are mounted on conveyershafts 31 and 35, being keyed thereto, and
the endless chain 37 in driving connection with said sprocket-wheels, is carried'during" its upper horizontal travel-in the guide-rail, 38 which is bolted to the. frame; andhas-an extension-guide 39 bolted thereto at the tie entrance of the machine, theguideand guide-plate forming also, a rail upon whichthe ties are conveyed through aportion-of' their travel through the machine. Pivoted extension dogs 40'are carried by chain 37, the dogs having a front andrear pivotal support and have a head 41 adapted to engage a tie. A cutter-head shaft. 43 is journaled in the journal-bearings 44 bolted to.
the. top of the cutter casing. and has fixedly.
secured thereon a suitable forrnofcuttinge head 45 disposedin the-opening46in the top of said casing. .A pulley 471' fixed on one end of said shaft is driven through a-belt drive by the drive-pulley 42,.keyedlt the drive-shaft 25. Ashavihg guide48 i'spivotally mounted to the feed sideof the. cutter: and is held yieldingly against a tie passingv thereover by the spring 49, in order to guide all shavings being thrown thereagainst, into the cutter casingand out of the shaving discharge conduits 50. An. equalizing support is formed of [two-parallel support: ing bars 51 bolted together by the cross-bars 52; Supporting links53'havea pivotal connection with each crossrbar at 54 and'a, bifurcated end having a pivotal connection 55 with the eccentric-ring levers 56. lhe eccentric ring levers are mounted on eccentrics 57 fixedly secured to shaft 58 which is supported in bearings59 in the frame. Brackets 60 hold the links53slidable, and against lateral displacement. Adjusting levers 61 I are pivotally mounted on the. stands 62 and haveconnectionthrougli'rods 63 with crankarms 64 fixed with the eccentric-shafts 58, the rod 63 connectingW-iththe crank-arm on the adjustable carriage 13, havinga longitudinal adjustment to allow for movement of the carriage. Rods 65 have a fixed connection with each equalizing support at 54 and extend outward being connected with the rods 66 which rock the indicator fingers 67 carried by stands 62, therebyregistering when the equalizing supports have been pivoted, the angle of such pivoted position; Bolted to the. ends of each frame are standards 68 which carry rods 69 forming an overhead support. Secured to the standard carried by frame 14' is-the endIguide-plate 7 0 carried by a bracket 71 adjustable in the Ways 7 2, said guide-plate being set to center thetie'in relation to the cutting heads.
Means are carried above each cuttinghead for holding the ties in position during the gaining operation. A supporting bracket 73 is boltedto therods 69 and has upstanding cars which carry pivotally by pin 74, the cylinder 75 having a piston-rod 76 and pist0n'7 7 '(Fig. 10), said cylinder having openings 78, and79 at the top and bottoinfthere of, respectively. 1 Piston-rod 76 is provided with an adjustable stop-8O at its upper end,
and has apivotal connection81 at its lower end with the tie shoe 82. Tie shoe 82 has at itsentranee end, an oblique guide-plate 83, and a suitable lubricant receptacle 84 com municating-withthe guide face,- said' receptacle carryinga solution adapted to dissolve and'free said face from pitch or the like accumulating thereon from contact with ties. Tie-shoe 82 is supported by bracket 73 through the parallel connection comprising upper: and lower links 85 and 86 respectively, connected by parallel links 37, and the guide-.linksSS. This holding means is shownin, its inoperative position in Fig. 10 and a tie being fed through the machine will contact the guide-plate 83, raisethe shoeto a. position as shown'in the other views thereof, the air above the piston77 passingout .of-opening 7 8, theweight of the shoe being sufii'cient to hold the-tie during the] gaining. operation, and upon the tie. be i'ngconveyed away'therefrom, the shoewill drop to the inoperative position, but the drop willbe. aslow one as the fall will be cushionedby. the slow escapeofair from the lower. 1i0le79.v The adjustable stop limits the downward movement of the shoes.
Suitable conveyers89 are shownmounted onshaft 35, driven thereby, and adapted to car'ryties to the machine, and discharge conveyersl90 are similarly drivenby shaft 31- 'and' discharge-theties. When it is desired,
the gaining machine may be placed adjacent a tie-boring machine in such a manner that the ties continue their passage from the gaining machinedirectly to the boring niachine to'be the tie. I
t he main drive-shaft 25' is to be driven at a. high rate ofspeed in order to rotate cutter-heads 45. at the desired speed, while it will be seen that the drive through the belt andgea'r connections to the conveyer cutter-heads 45, and are then conveyed off of the equalizing supports and'discharged from the machine. 7
It will be seen inthe case of a set rotary cutter and a fixed. tie carrying rail, that bored in the gained portions of when a tie of an irregular shape is gained, very often the cutter will not gain a surface throughout the longitudinal length of the cutter because of such irregularity in the tie, but will cut deep on one end of the cutter and not contact the tie with its other end. By providing our equalizing supportsthis defect is overcome, and inFig. 5 we have illustrated a tie irregular in shape showing the action of said equalizing-supports.
Illustrating a particular case, assume a machine of the set cutter and fixedtie rail type, and the cutters set to gain a portion inch in depth, that is, the cutter face is set i; above the rail. A tie is conveyed thereover, being irregular in shape so that the proposed surface to be gained is not parallel with the cutter face. A cut 7 inch deep is taken, but it only covers one-half the width of the cutter because of the incline to the surface of the proposed gained portion of the tie. With an equalizing support, in the place of said fixed tie-rail, and the cutter set in the same position and cutting depth, when a similar irregular tie is conveyed thereover, the equalizing support will pivot, dividing the irregular distance between each end of the cutter and the face of the tie, and lower the tie one-half this distance, thereby gaining at the center portion of the cutter g}: inch deep and throughout the length of the cutter to a varying depth resulting from said irregularity. I
The indicator fingers 67 show at what angle the equalizing-supports are tilted, and if such irregularity of the tie is indicated to be so great that an entire cut will not be taken, the levers 61 are operated to lower the equalizing supports until the indicator finger is within a predetermined point. It will be understood that as in the above illustrated case, levers 61 would be set for a cut 3; inch and the indicator finger wouldhave a certain range of movement correspondingv to irregularities of ties that would be gained the length of the cutter with this set position, and that said levers would be operated only when the indicator-fingers went beyond this limit.
In moving the adjustable carriage over the base by the hand-wheel 15 the several coacting instrumentalities operating upon that end of the tie, with the exception of the tie holding means indicator fingers and their control levers which may be movable by loosening set-screws holding it fixed on rods 69, are moved bodily, thereby maintaining the relative position of one instrumentality to the other, and retaining a center of operation regardless of said movement of the carriage over the frame.
The vertical adjustment of the equalizing support could be accomplished by operating means of other constructions than that disclosed herein, for instance, means for automatically raising or lowering the supports, without departing from the scope of our invention.
